Clock spring mech is prob bad, first easy check is remove airbag 2 8mm bolt from back side of wheel make sure wires are still connected if they are good the clock spring mech is bad you can use a steering wheel puller to remove wheel and clock spring mech just snaps out and has 2 plugs on it, I have 2 if you need one.

Your vehicle has 2 ignition wires that you can put back to factory, and start the vehicle.
The wires you are looking to put back together are (blue) and (black/orange) - and found under the D/S dash. (ignition harness) They will be larger in Diameter than the others.
They were cut to install the security system. They go into the "brain" and out the other side. A relay inside the BRAIN is most likely failing.
If you no longer want the alarm installed, simply match up all of the factory colors. Use crimp-on ****-connectors for secure connection.
Let me know if you need more help.

May be bad horn. Get a 12 volt test light or multi-meter and attach to the horn wire at the horn. Have a helper press the horn. If you have 12 volts when it is pressed, horn itself is bad. Otherwise, may be bad horn relay. Horn cover should pull off.

Are you check fault codes there? First check, no crank or no start condition is an easy thing to diagnose. Beyond the battery
stuff, you need to know if power is at the starter solenoid, and being
switched to the starter motor with the key in the crank position. Rrequires two people and a test light. If power goes to the starter
motor, and no crank, then starter is bad. If no power there, then there's
issues with wiring, fuses, ignition switch, clutch switch and so on.
Remember the basics for no start issues. An engine needs three things to
run normal:
1) Compression
2) Fuel
3) Spark
At some point, your not getting one of those three things. First,
isolate the problem. Will it crank over? If not, probably battery or connections, or locked
up starter, etc...
It will crank but not start - very common. Crank it over for a few
seconds and pull one spark plug, is it wet with gas? If no, then your
not getting fuel. If yes, your not getting spark. Test for spark with
the plug out, if no spark, focus on the electrical systems. If there is
spark, focus on the fuel system. This narrows your troubleshooting by
50% to not waist time.
Based on spark or no spark, you should be able to continue
troubleshooting each system. For no spark, check coil, check wires,
check ignition, check grounds, test each component, check for wore wires
sparking on the block before it hits the plug, change plugs, change
distributor cap and rotor, etc... Somewhere, there will be a breakdown
in the system.
For no fuel, check your fuel pump (does it growl when you hit the key to
on?), fuel filters, power to the injectors, fuel lines, etc...
In the rare case that you do have spark, and you still have a wet spark
plug, there is most likely water in the fuel system or your plugs are
fouled and should be replaced.
Just the basics I can think of off the top of my head... Most of the no
start issues I encounter are either an old battery that will not keep a
charge anymore (usually older than five years) or loose cables. Loose
cables and dirty terminal connections make up about 90% of the problems
with starting. ALWAYS check those first, pull 'em off the battery and
clean with sandpaper or a wire brush to ruff 'em up really good. Same
inside the terminal connector then lock 'em down.
You need to do a little investigating. Run it for a while to get the
engine warmed up, then shut it off somewhere that you have some test
equipment and help available. Make sure it won't start, then spray a
little starting fluid into the air intake while a helpe tries to start
the engine. If it starts briefly you know that there is a problem with
fuel delivery and you can start checking out the filter, fuel pump,
relays and electrical circuits that feed the fuel pump. Remember that
even NEW fuel pumpscan have a problem so don't rule out that one.
If it WON'T start with the help of starting fluid, pull a sparkplug wire
and connect it to a spare sparkplug. Set the spare sparkplug with the
wire attached on a metal part of the engine and have your helper try to
start it again. If you don't have a nice, strong spark, you know there
is a problem in the ignition somewhere. If there isn't a spark, check
the coil input. Connect one end of a volt meter to ground and the other
end to the coil input. One side of the coil input should have constant
voltage, the other side should be intermittent while the engine is
cranked by your helper. If you're getting voltage TO the coil and
intermittent voltage on the other side, but no spark, you probably have a
bad coil that fails when it gets hot.
Good luck.

The horn relay is located in the Intergrated Power dist Box, This is a Cherokee, but you get the idea.
